Parts of the Pope's Pilgrim Fellowship of Faith: The Church as Communion read like a bible study! Very rich. On 1 Cor 6:12-19:
According to this text, receiving the Eucharist means blending one's existence, closely analogical, spiritually, to what happens when man and wife become one on the physical-mental-spiritual plane. The dream of blending divinity with humanity, of breaking out of the limitations of a creature - this dream, which persists through all the history of mankind and in hidden ways, in profane versions, is dreamed anew even within the atheistic ideologies of our time, just as it is in the drunken excess of a world without God,--this dream is here fulfilled. Man's Promethean attempts to break out of his limitations himself, to build with his own capacities the tower by which he may mount up to divinity, always necessarily end in collapse and disappointment - indeed, in despair.
This blending, this union, has become possible because God came down in Christ, took upon himself the limitations of human existence, suffering them to the end, and in the infinite love of the Crucified One opened up the door to infinity. The real end of creation, its underlying purpose - and conversely that of human existence as willed by the Creator - is this very union, "that God may be all in all."
